Add optional parameters for enabling LDAP authentication for TRIBE using LDAP3

• Ability for user to toggle between default authentication vs LDAP authentication (AUTHENTICATION_METHOD parameter, defaults to the current implementation) - Options (default, ldap) - can add more options as needed
• Ability for user to specify the following configuration options if LDAP is enabled
• LDAP SERVER/PORT
• LDAP search base
• LDAP search filter
• LDAP TLS enablement
• LDAP Cert path
• LDAP TLS path

Hi @acherla, I'm not very familiar with LDAP. What are the benefits of having this as an option?

Its normally used by enterprises that have an active directory management system for providing groups or organizations within a company access to a system.
